Buckeyes on rise, Nittany Lions have questions, Oklahoma humbled.

We won’t be certain until the Pac-12 wraps up its late games on Tuesday, but the big Week 6 winners appear to be Ohio State and a Pac-12 team to be named later.

That’s because Iowa State took down Oklahoma, which had conquered the mighty Buckeyes, And who said, “See ‘ya later, Sooners?’’ None other than Cyclones coach Matt Campbell, who was Tim Beckman’s offensive coordinator when Illinois hired the wrong guy from Toledo.

Oklahoma’s shocking misstep opens the door for a West Coast team to join Alabama, Clemson and a Big Ten team in the four-team College Football Playoff.

Of course, there’s a ton of football to be played, and none of those teams can afford to look ahead. Washington and Washington State are tracking for a top-notch Apple Cup. Unbeaten TCU has every right to say, “What about us?’’ And if Georgia keeps playing the way it’s playing, there will be discussions about scenarios in which two SEC teams are judged playoff worthy.

See? Players and coaches can’t look forward. But we can. And here’s what we see.

If you watched Penn State slog past punchless Northwestern on Saturday the way I did, and looked beyond the 31-7 final score, you probably had this conclusion: For all their hype, the Nittany Lions did not do well on the eye test. Yes, Saquon Barkley is going to make some NFL team very happy. But Northwestern stuffed him all day, except for one play, due to wobbly blocking. Here’s my Chicago Sun-Times report.

The Penn State defense was solid. But overall, Penn State didn’t dazzle. Throw in the heroics the Nittany Lions needed at Iowa, and this is a team that could have its hands full at Michigan State as well as Ohio State.

Oh, and by the way, Sparty knocked “big brother’’ Michigan from the ranks of the undefeated.

That’s two teams that were ranked ahead of Ohio State that lost, if you’re keeping score at home. And the Buckeyes will have an opportunity to add a third vs. Penn State in Columbus on Oct. 28. The rest of this article is available to subscribers only – to become a subscriber click here.
